[Crash-utility] using crash for ARM

[paawan oza]

Hi Dave,

Will I be able to set breakpoints and watch points in kernel space ?
Do you accept the changes/contribution to crash ?


Regards,
Oza.

If you are talking about running crash on a live ARM system, then
option #1 is the only possibility.  Option #2 does not exist for
the crash utility; live system access requires either /dev/mem,
/proc/kcore, or the /dev/crash misc driver.
